I need to replace emblems and registration number on the boat this winter. What's the hive mind think? Gold or Chrome?

Does this engine need to be link and synced?

This is my dads boat and it’s been in the family for years. Almost none of the electronics work or any safety equipment. I’ve slowly been getting everything in working order and keep coming across real head scratchers. At some point the transom was repaired with a welded plate on the exterior nothing interior that I can find. The ugly bubbly spots are me with some metal filler on some corrosion then paint over it but keep getting these white little strings that come through all the work I did. My main concern here though is where do I plumb the bilge pump to? I have now realized that it is currently plumbed to the live well tank but there’s no holes anywhere in the boat except a live well drain. The story my dad has always told us was that it used to be an old fwc (Florida wildlife commission) boat. I don’t know where else to plumb the bilge to or the aerator except to drill holes correct? Any helpful criticism would be greatly appreciated as I am learning all of this stuff. Sorry for the long post.
TLDR: help me find where to plumb the bilge to/from

This is the only location on this boat that cables can be ran through. There was some used to be plastic tucked in there but I needed to rewire everything and it was hard as a rock. So I’m trying to replace it. The only thing I found was this trim insert for rvs and can’t find anything bigger I have searched and searched but maybe the internet can help me here. Any help would be appreciated

Trying to put new flooring down on the boat. Everything I’m finding is just for a 07-08. Every company keeps sending me the same layout which looks very similar just not sure. Anyone here have the same boat and replaced the flooring? If so what did you use?

Any repowered recently?
Im curious the brand, the hp and the price. Most importantly, why did you do it?

Does anyone have any advice how to do this?

3-phase berths are 20m (boat 16m) and double the price. They want to move me there.

Is there any way to keep Genset 3-phase and also make the boat work with single phase marina power?

I am noobie, excuse me if I left details out. Boat has 86,000 btu A/cs (4 total). Houseboat.

NOTE: I have already called electricians for this. But I want to be be informed about the choices I have.

Thanks!
